IRRIGATION PUMP.

application filed July as, 1921.

To alt whom it may concern Be it known that l, Crmiinns W. Claire nnLL, a citizen of the United States residing at Chappell, in the comtity cit l'leuel and State of Nebraska, have invei'ited certain new and useful improvemen s in irrigation .lPumps, oil which the tollowing is a speciiioa tion, reference being had therein to the accompanying drawing.

My invention relates to improvements in irrigation pumps, the primary object oi which is to provide a pump which will re quire a relatively low motive power for operating it,

ltleretoiore, various types oil pumps have been devised for use as irrigation pumps and particularly the centritugal type of pump. This type of pump has been found to require a large amount 0t power relative to the pumping capacity and they have proven unsatisfactory.

it further object oi: my invention. is to provide a plurality of screw-pumps throughout the depth of the well which are simultaneously operated and one pump forcing the Water tothe pump or pumps above and finally delivering it to the desired irrigation point.

A further object of my invention is to provide a plurality of pumps operated by a common shatt which extends through the depth ot the welh the pumps located at ya rious points from the bottom t substantially the top of the well, the puu'ips located distances apart increasing from the bottom to the top of the well.

another object of my invention is to provide a pump for irrigation purposetn which comprises a plurality o t screwq'imnping incchauisms, which are placed in con'uuunication through spirally arranged tubes between the several pumping mechanisms.

Another object ot my invention is to pro vide a pump for irrigation purposes, comprising a plurality (it screw-like pumping mechanisms located varlous points Another object olmy invention is to provide a pump for irrigation purposes, comprising a plurality of screw-like pumping mechanisms arranged throughout the depth of the well. and simultaneously operated, the lowest pumping mechanism having a greater number oi outlet openings in communication with the pump above than the upper pumps have, whereby the increased capacity is obtained.

.atnother object of my invention is to provide means tor indicating separately the pumping pressure oi the several pumping mechanisms, so that the pumping efficiency or one oi the mechanisms can at all times be ascertained.

Another object oi my invention is to provide an irrigation pump, consisting of a plurality of pumping mechanisms located throughout the depth of the well and simultaneously operated combined with a separate telephone communication with the various mechanisms so that any diiiiculty in the operation of the system. can be readily detected and located.

Another object of my invention is to provide a pump for irrigation purposes, comprising a plurality of pumping mechanisms and means tor providing lubrication tor the lower pumping mechanism which will be circulated and distributed throughout the several pumping mechanisms.

tlther objects oi my present invention will appear from the disclosure and the tollow- Zing description.

in the accompanying drawings Figure l is vertical section of the upper end ot a well showing the upper part of my improved pump in side elevation.

5- is a perspective view showing the latrines sl'iown) may or may not be used for controlling; the How oil? the oil from the reservoir 37.

Located within the housing a, are a plurality of pressure gauges 39, which correspond in number to the number of pumping mechanisms, and each pressure gauge communicates respectively with one ot the pumping mechanisms by the pipes 40, whereby the pressure of the separate pumping mechanisms may be at any time determined, which will enable any ineiiiciency to be located. llt will be understood, of course, that there will be a pressure gauge for each pumping mechanism, and this will vary according to the number of pumping mechanisms used in the well.

The number of pumping mechanisms used in the well will diileraccording to the depth of the well.

For the purpose of locating any breakage or irregularity in any of the mechanisms, l

3 provide a plurality of telephone communications, separately connected wlth each pump mg mechanism. These telephone mecl'im nlsms are d1agrammatically shown in Fig.

6, and the receivers shown in E2. The recelvers ll are electrlcally connected through batteries 42 with the screw-pump inp; barrels 10, and the receivers are located on the board 43, which also contain the pres sure gauges 89. These telephone systems will. be of the ordinary construction, which are well understood and do not need any specific description or further illustration ll hen the receivers ll. are li'lted, the electric connection will be made in the ordinary way, so that the operator can listen in upon any of the pumping niechainsms, to

determine whether there is unusual noise in them.

The housing 4 is provioed with a suitable door eldthrough which access can be had to the instrument board el-S.

Attention is directed to the tact that the pumping mechanisms at the lower portion ot the well are closer together than those of the upper portion ol the well, as indicated by comparison ct Figs. l. and l By this arrangement, the pumping ca mcity is any ,lncr wed because tl'iere a shorter distance to hit the water to the mechanism aliiovc,

By a pump or this ctuistruction, water can be lif ed from a well of any reasoualiilo depth and with eliiciency. 'l hc pumpiur arrangement may be made in sections so that they may be increased or decreased in ninnhers according to the depth of the well.

My irrigating pump delivers the water in quantity and with force into the pipe 35, and by connecting); a hose with this pipe it can advantageously and efliciently be used as a lire-engine to extine'uish ii l lspecially is this true when the pump is located within hose reach or" the house or other buildings on relatively small tracts o'l land which are being irrigated. The pump will deliver a strong stream of water through a nozzle which will be efi'ective tor extinguishing fires.

l do not limit myself to the exact con struction and arrangement ct parts shown and described herein, as these may be varied by persons skilled in the art without dcparting from the spirit and scope oi? my invention, and what l: claim ice-- 1. it pump of the character described, comprising a plurality of pumping mecha nisms located in the well, one above the other, the pumping mechanisms comprising each a barrel and a screw-pump therein, the barrels having spiral outlets and spirally arranged tubes communicating with the outlets ot the pumps below and the inlets cf the pumps above, and means for simultaneously rotating the pumping screws.
